How do you calculate coating cost per pump?

Multiply pumps by per-pump cost by the full-system share, add fixed booth and prep cost, then divide by pumps. For 60 pumps at $140 with 100% full system plus $1,200 booth cost, total is $9,600 or $160 each.

Why is per-pump cost higher than the coating rate I entered?

Fixed booth and prep are spread over the lot. At $140 variable and $1,200 fixed over 60 pumps, per-unit cost is $160 - the extra $20 is amortized booth and masking. Bigger batches shrink that adder.

What does 'share receiving full coating system' mean?

The percentage of the lot getting the complete multi-coat system versus a partial or single-coat finish. Set to 100% when every pump gets the full spec; lower it for mixed-spec lots.

How can I reduce coating cost per pump?

Increase batch size to dilute the $1,200 fixed cost, reduce masking and prep time, or improve transfer efficiency to cut material waste in the variable rate.

Does this include surface prep like blasting?

Blasting and masking belong in either the per-pump variable cost or the fixed prep cost, depending on how your shop books them. Be consistent so you don't double-count or omit prep.

Total coating cost vs cost per pump - which matters?

Quote total cost on the job; use per-pump cost for margin and to compare against a target finishing cost per unit. This calculator returns both from the same inputs.

Coating cost per pump Calculator

Coating cost per pump is the fully loaded cost to surface-treat a batch of pumps - epoxy, fusion-bonded, or multi-coat systems for corrosion and abrasion resistance - combining variable per-pump coating with fixed booth and prep cost. Finishing supervisors and estimators in pump manufacturing use it to quote coating jobs and to right-size batches so booth setup and masking aren't wasted on tiny lots. Because some pumps in a lot may need only a partial coat while others get the full system, the calculator weights variable cost by the full-system share. The output is a defensible total plus a true per-pump cost that carries the fixed booth and prep you'd otherwise under-allocate.

What this calculator does

Estimate coating cost per pump for water and wastewater systems from run size, per-pump coating cost, the share needing the full system, and fixed booth adders.
a pump shop needs to cost epoxy or fusion-bonded coating for a batch of casings before quoting or scheduling the booth
It computes total coating cost as quantity times per-pump cost times the full-system share, plus fixed booth and prep, then divides to a per-pump figure.

Formula used

Total coating cost = pumps to coat x coating cost per pump x share receiving full coating system + fixed booth and prep cost
Coating cost per pump = total coating cost / pumps to coat

Inputs explained

Pumps to coat:
Coating cost per pump:
Share receiving full coating system:
Fixed booth and prep cost:

How to use the result

Use it when quoting a coating job or deciding a batch size that amortizes booth setup and masking effectively.
One blended per-pump cost and a single full-system share won't capture wide differences in surface area or coating spec; segment the lot when pumps vary materially.

Current U.S. benchmarks

The U.S. has 21,668 machinery manufacturing establishments employing about 1,086,146 workers (Census County Business Patterns, 2023).
